This invention relates to transition car couplings `and provides a novelform of cou-V pler whereby ai coupler of the European lhook type may beeasilyandeffectuall con nected with an automatic coupler. yT e 1nventionprovides a device Whlch maybe Y readily assembled or disassembled butwhich cannot be easily lost, which will accommodate itself to the bufingposition of the cars, and which will be out of the way when two carsequipped with auto-matic couplers are to be coupled. Theinvention isillus-y trated inthe accompanying drawings and consists in certainynovel features which -will be hereinafter first fullyl described andthen more particularly pointed out in thefappended claims.

In the draw1ngs,'Figure1'isa plany view ofthe invention applied inworking position. t

Figure 2 is a side elevationof the same. Figure 3 is a side elevationshowing how the'device accommodates itself tothe buiiing position of thecars. v

Figure 4 is a view similar to Figure 3 but showing a different loadrelation of the cars, an v Figure 5 is a side elevation showing theposition assumed by the device when the cars are uncoupled. .Y y

In the drawings, the reference numeral 1 indicates a drawhead having theY' usual knuckle 2 and a guard arm 3, and 4: indicates the hook portionof the hook type coupler. In accordance with the presentv invention,theguard arm is open at its front end and at its bottom thereby providing a"chamber or recess in which the. coupling device 5 is fitted andoperates. Thel coupling device, indicated as an entirety by thereference numeral 5 consists of a rod 6 hav.

retained therein by apin 10 inserted through the side of the arm andsecured by a key 11 passed through its outerend and lugs or ribs 12 onthe arm. By this arrangement, the buiing surface 13 and thelock housing14e of the drawhead'are not disturbed nor weakened so that the presentrelations of the working parts of the automatic coupler herein. tionwith the automatic coupler, allows the PATENT eni 'f WOLFE,orcoLUMBUsoHIo, 'AssIGNon fro T HE suenan; STEEL `CASTINGS COMPANY,oFcoLUMBUs, oHIo. i

are maintained.-A The rod 6 is provided with i pling rod '6 or toeXtendradially therefrom.

This lever or `handle bar 17 isV used for the purpose of screwing thecoupling rodV 6, which is threaded right and left, through theheads 8thereby shortening or lengthening thedevice.` The 'device mustpbeextended before it can be applied on therhook and lafter it is appliedit is shortened tobring about tension in the side buffer springs..

`This device is a part of the present hook couplingY and when anautomatic coupler is' installed on a vcar the 'screw couplingis`fremoved from the hook and secured to the automatic coupler as shownandd'escribed The use of this device, in connec-A automatiecoupler tobecoupled up with the hook coupler while the cars are in motion, andwhentheyare not coupled or both cars are equipped with j automaticcouplers it may depend from thev drawheadout of the i 1 Way, as shown inFigure 5. As the retaining and pullin pin 10 is located at one side r yof the longitu inal center line and back of susl the'pulling face of thedrawhead, there is j no interference with the air hose connection.

VTo assemble the parts,`one yoke 9 is inserted inthe recess or vchamberof the guard armand the Vpin 10 theninserted through the side oftherarmand through the yoke land locked by the'key, rivet or bolt 11, thedevice being then ready for use. A reverse operation will disassemblethe parts, and it willY be readily noted that it is'not necessary Vtoplace theL carin a shop for-either operation. o A

A Shouldl fthe cars come together while coupled, the yokeo9 and rod 6will fold sov downwardly, as shown in Figures 3 and 4,

so that no breakage orl other damage to the 1n the Vguard arm issolocated as to permit suchl movement of the coupler to accommodate thespring travel of the cars. f
